The latest escalation in U.S.- Canada trade tensions has created an immediate challenge for Canadian companies that depend on the United States as a customer, supplier, or manufacturing partner.
On August 22, the United States enacted new 50% tariffs covering approximately $20 billion of Canadian products after negotiations between the two countries broke down. Canada has announced plans to respond with tariffs on selected U.S. goods beginning September 8.
For Canadian businesses, the impact extends beyond the tariff itself. Companies must now evaluate how higher costs, changing customer behavior, and potential supply-chain disruption could affect their competitiveness in the U.S. market.
The immediate challenge for Canadian exporters
A U.S. tariff is generally paid by the U.S. importer. However, the commercial cost is often shared across the supply chain.
U.S. customers may ask Canadian suppliers to reduce prices, absorb part of the tariff, renegotiate existing contracts, or move production to the United States. Some buyers may begin looking for domestic or alternative foreign suppliers.
This puts Canadian companies in a difficult position. Absorbing the tariff may protect customer relationships but reduce margins. Passing the full cost to the customer may preserve margins but make the Canadian product less competitive.
Companies should begin by determining:
- Which products are covered by the new tariffs
- Which U.S. customers and contracts are affected
- Who is responsible for tariffs under the agreed Incoterms
- Whether current pricing remains commercially viable
- Whether goods already in transit are affected
- Whether customers are likely to change suppliers
USMCA qualification may not provide complete protection
Canadian businesses have historically relied on the United States-Mexico-Canada Agreement to support duty-free access to the U.S. market. The new measures demonstrate that USMCA qualification may not always protect a product from an additional tariff action.
Companies must evaluate two separate questions: Does the product qualify under USMCA, and does the new tariff still apply despite that qualification?
Canadian exporters should also confirm that their origin certificates, bills of material, supplier statements, and production records support any USMCA claims. Inaccurate or incomplete documentation can create additional risk for both the exporter and the U.S. importer.
Canadian retaliation creates another layer of cost
Canada’s planned retaliatory tariffs may help place negotiating pressure on the United States, but they can also increase costs for Canadian businesses that import U.S. products, equipment, or materials.
Some Canadian companies could therefore be affected in both directions: their exports may face tariffs when entering the United States, while their U.S. inputs may face tariffs when entering Canada.
Manufacturers with integrated supply chains are particularly vulnerable. A component may cross the border several times before becoming part of a finished product, multiplying the potential cost and administrative burden.
Key business risks
Canadian companies should prepare for several possible consequences:
- Reduced demand from U.S. customers
- Pressure to lower prices or share tariff costs
- Higher costs for U.S.-origin materials and equipment
- Contract disputes over responsibility for duties
- Delayed shipments and additional customs reviews
- Increased documentation requirements
- Pressure to move sourcing or production
- Uncertainty surrounding future negotiations
Industries such as automotive, steel, manufacturing, electronics, appliances, dairy, and consumer products may face particularly significant exposure.
How Canadian companies should respond
The first priority is to quantify the financial exposure. Companies should review product-level sales and customs data to identify affected products, customers, and transactions.
They should then evaluate possible responses, including:
- Confirming product classifications and countries of origin
- Reviewing USMCA qualification and supporting records
- Reassessing pricing and customer contracts
- Evaluating alternative suppliers and production locations
- Reviewing Canadian duty-relief and remission opportunities
- Considering bonded warehousing or duty-deferral programs
- Assessing whether refunds or drawback may be available
- Developing alternative U.S. market strategies
Canadian businesses should also coordinate with their U.S. customers. In many cases, the U.S. importer will hold the customs-entry data needed to calculate the tariff impact and evaluate potential mitigation strategies.
Turning uncertainty into a plan
The current environment requires more than monitoring news announcements. Canadian companies need to understand how the tariffs affect individual products, contracts, and customer relationships.
A structured tariff-impact assessment can help management answer the most important questions: How much exposure does the company face? Which customers and products are most vulnerable? What costs can be reduced? Which commercial decisions must be made now?
Leyton’s Global Trade Optimization team can support Canadian companies with tariff-impact assessments, classification and origin reviews, USMCA analysis, customs-data reviews, duty-relief strategies, and supply-chain scenario planning.
The companies that act early will be better positioned to protect margins, communicate with customers, and respond as North American trade policy continues to evolve.
